FIELD OF THE INVENTION

The field of the invention relates to multi-user online gaming systems,and more particularly to systems and methods that enhance the experienceof players and spectators for online active games.

BACKGROUND OF THE INVENTION

Like any popular competitive activity, such as football, basketball,card games and board games, multiuser online games have a largefollowing of fans who appreciate competitive games and highly skilledplayers. Further, like with other games, such fans enjoy beingspectators to highly competitive games or games that certain players areparticipating in. Further, there is a particular desire to witness thesegames live, particularly in organized tournaments. For example, in onepopular multiplayer online game, League of Legends from Riot Games(www.leagueoflegends.com) from a base of millions of active users, thereare a handful of players who have become famous for displayingexceptional skill and strategy. When these players engage in a gamesession, League of Legends enables other players to be spectators to theactive game session. However, it would be desirable to improve thecurrent spectator experience, for example, with an enhanced userinterface. In addition, the players in the game session often need toview the information of the game play, for example, statuses andconditions of other players. Accordingly, systems and methods to enablean improved spectator's and player's experience would be desirable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS State of the ArtSystems

Turning to FIG. 1 a, a large multiuser online game system 100 over apublic network 1050, such as the Internet, is shown. An example of sucha game system 100 known in the art is League of Legends(www.leagueoflegends.com). League of Legends is a session-based,multiplayer online battle-arena game where rival teams compete againstone another for victory on highly stylized battlefields and landscapes.Users can install a League of Legends game client on their personalcomputing device 110 to establish a game session over the public network1050 with the game system's 100 datacenter 130, which provides thereal-time online game interaction with the plurality of users 110.

Turning to FIG. 1 b, an example game client 110 user interface is shown.In online games such as League of Legends, each user is generallyrepresented by a personalized graphical avatar in the user interface,also referred to as “champion,” (shown as “X” in this example), and thegame client 110 user interface may show the logical position of oneuser's avatar, X User 1, relative to another, X User 2 and X User 3within a virtual landscape. The game client 110 user interface may alsoinclude a chat interface (“Chat Room”) that enables participating usersto communicate with one another beyond interactions with the avatars(Xs).

The datacenter 130 (FIG. 1 a) includes a plurality of server systemsoperating on a plurality of server machines communicatively coupled toeach other via the public network 1050 and/or a secure virtual privatenetwork (not shown). The server machines each includes one or moreprocessors, memory, an operating system, one or more input/outputinterfaces and one or more network interfaces all known in the art.According to an embodiment, the datacenter 130 includes, among otherthings, a game session server system 140.

Turning to FIG. 1 c, a more detailed diagram of a game session serversystem 140 known in the art is shown. The game session server system 140provides the game interaction with the users' game client 110 via thegame client interface 143, which is generally an application interfaceknown in the art accessible over the public network 1050 by the gameclient 110, e.g., in a traditional client server model. A game engine142 coupled to the game client interface 143 is included to manage theinteraction among the plurality of users 110, and between the pluralityof users 110 and the game system 100. As one of ordinary skill in theart can appreciate, highly stylized user interfaces often containgraphics requiring large amounts of data. Transmitting such graphicsover the public network 1050 may cause slow performance due to thelimited available bandwidth of the public network 1050. One approach toaddress this is to have the graphics rendered by the game client on theuser's computing device 110. To account for movements and changes toplayers in the game, only certain information is transmitted over thepublic network 1050 between the game clients 110 and the game engine142, e.g., coordinates of various players within the landscape of thegame.

Turning to FIG. 1 d, such data can be transmitted efficiently in blocksof data packets collectively known as “chunks,” an example format ofwhich is shown in FIG. 1 d. A chunk 150 generally includes the latestcoordinates within the virtual landscape of certain users, a time stampto enable the game engine 142 to synchronize data among players, andadditional game data to facilitate rendering, such as weapons and powersthat have been added or removed or other information to reflect thelatest state of a player's avatar. A game client 110 will use the datain the chunk to render, among other things, the appropriate graphics andvisual representations of the positioning of the avatars within thevirtual landscape. If a user makes a change to its avatar state on itsclient 110, e.g., if the user moves its avatar or adds a power, one ormore chunks 150 may be transmitted back to the game engine 142 to updatethe remaining players and to update rendering on the devices 110 of theremaining players. The chunk 150 enables responsive, high-performancereal-time game play with highly stylized graphics over a public network1050 of limited bandwidth since the graphics are rendered on the gameclient 110 and only limited data is transmitted for game interaction. Inan embodiment, a chunk 150 for a particular user will not include alldata for the game session but only data limited to the user's view. Forexample, turning to FIG. 1 b, a rock or tree may hide another avatar inthe virtual landscape from the first user's view. To maintain thiscontext and competitive play, the hidden user's coordinates may not beincluded in the chunks sent to the first user until the hidden user isrevealed during game play (e.g., the other user may move its hiddenavatar into an opening unblocked by the rock or tree).

Turning back to FIG. 1 c, the game session server system 140 furtherincludes a chat engine 144 known in the art that enables the varioususers at game clients 110 participating in a particular game session tocommunicate with each other via text messages. Audio, pictures, andmultimedia may also be exchanged with the chat engine 144. Both the gameengine 142 interactions as well as the chat messages exchanged can berecorded and stored in a game files database 141. This enables, amongother things, replay and history analysis by not only the users but alsothe administrator and other systems as will be described below.

Preferred Systems

Turning to FIG. 2, an online multi-user game system 1000 according to anembodiment of the present invention is shown. The system 1000 providesan enhanced player and spectator experience as will be described below.The system 1000 includes a datacenter 130 having a game session serversystem 140 as described above. The system 1000 also includes gameclients 110 configured to access data center 130 over the public networkas described above. According to an embodiment, the system 1000 furtherincludes a spectator grid 1100 operatively coupled to the game sessionserver system 140 that enables a user with a spectator client 1200 toaccess the data center 130 and select an active game session to view asa spectator. The spectator grid 1100 is also implemented as a serversystem. The spectator client 1200 includes a similar graphics renderingapplication as the game client 110 but with no ability to activelyparticipate in the selected game.

Turning to FIG. 3, a detailed diagram of a spectator grid 1100 is shown.The spectator grid includes an in-game database 1110 that is configuredto receive game data, e.g., game chunks 150, from the game sessionserver system 140 via a game session server interface 1120. These gamechunks 150 may include global data, e.g., positioning coordinates foravatars whether hidden or not, within the virtual landscape of a gamesession. The in-game database 1110 may utilize an in-memory coherencecache, thereby enabling faster querying of the database 1110 in realtime. The spectator grid 1100 further includes a spectator engine 1130configured to interface with spectator clients 1200 via a spectatorinterface 1140 and provide game data to the spectator clients 1200 fromthe in-game database 1110.

Preferred Processes

Turning to FIG. 4, a process 2000 according to an embodiment is shown.As mentioned above, fans of certain multi-user online games may wish tobe spectators of particular active games, as with any competitive game.To address this need, the game system 1000 enables a user to view activegame sessions within the system 1000. Turning to FIG. 5, an exemplaryinterface for a spectator client 1200 is shown. When a user connects tothe data center 130, one or more lists of active games are provided.They can be grouped into a variety of categories, including, activegames having the most spectators, active games played by most requestedplayers, i.e., players that most spectators have requested viewing of,e.g., players known as having exceptional skills. The data that enablethese lists can be tracked and deduced by previous spectators'selections, which can be stored in the database 1110 of the spectatorgrid 1100. Games can also be presented by specific game identificationand/or player identification (regardless of whether such a player iswell-known). Moreover, the game system 1000, e.g., the spectator grid1100, can monitor certain activities within an active game. For example,the spectator grid 1100 can monitor for games having scores that arevery competitive, for games that have a particularly high number ofknown or higher tiered champions, for players that are playing at aparticularly high level, and/or for players that are demonstratingparticularly unusual and/or entertainment techniques or moves. Thespectator grid 1100 can identify such games as recommended games forpotential spectators. Games can also be listed in random order. Gamescan also be listed by particular events, e.g., an organized tournament.

Turning back to FIG. 4, once a spectator has selected a particularactive game to view, the spectator grid 1100 receives the request(Action Block 2100) and establishes a data connection with thespectator's client 1200 (Action Block 2200) to transmit game data to theclient 1200 in streaming fashion (Action Block 2600) to be rendered onthe spectator client 1200 in real-time or near real-time to the selectedactive game. Turning to FIG. 6, an example format 1500 is shown for gamedata transmitted by the spectator grid 1100 to the spectator client1200. What is shown, in an embodiment, is that game chunks 150 are sentto the spectator client 1200 with similar structure and content to thegame chunks 150 sent to game clients 110. One difference in thisembodiment is that the game chunks 150 sent to the spectator client 1200includes complete data for the active game being viewed. For example,all player positions are provided, including the ones that are hidden,so that the spectator is provided an omnipresent view.

Once the chunks 150 are received, the spectator client 1200 can generatethe same graphics and visual representations of the active game inreal-time or near real time of the active game.

Also included in the data format 1500 are keyframes, which areeffectively snapshots of a particular game at a particular point intime. A keyframe is aligned with a fixed group of chunks 150, e.g., 3,to define a time interval using the time stamps in the chunks 150. Akeyframe can be generated by creating a chunk 150 that includes gamedata packets for all players that exist at a given time. When a keyframeis loaded onto a spectator client 1200, then the latest game data, e.g.the latest scene, along with all of the entity data that are known bythe spectator client 1200 at that time, e.g., avatar and computercontrolled object data, are deleted. The keyframe can then be playedback as a regular chunk 150, which renders the entity data that exist atthat point in time at their correct positions. The chunk 150 thatcorresponds to the keyframe's point in time is then loaded as the nextchunk to render. From there, chunks 150 can be rendered in chronologicalorder. The amount of game play time represented by a chunk 150 isconfigurable by the system's 1000 administrator, for example,approximately 30 seconds.

One aspect of the keyframes is the enablement of time-shifting featuresfor the live game (Action Block 2700). For instance, an active gamesession rendered from the chunks 150 at a previous point of time can bequickly simulated by jumping to specific keyframes instead of individualchunks 150. In an embodiment, when jumping to specific keyframes, muchof the game processing can be disabled, such as rendering and sound, toenable faster jumps. Once a keyframe is reached, then normal playbackand rendering is enabled, as described above.

Turning to FIG. 7, to illustrate exemplary time shifting controlsenabled by the system 1000 (Action Block 2700), a user interface for aspectator client 1200 viewing an active game session is shown. Asmentioned above, the chunks 150 enable the spectator client 1200 torender real-time, or in near real-time fashion, game play from an activegame, but with an omnipresent view that enables the spectator to viewall game play within the virtual landscape. Moreover, certaintime-shifting controls can be enabled. The following are examples.

Jump Back 1210—This button allows the spectator to jump back a fixedamount of time, similar to an “instant replay” feature. In this case,the spectator client 1200 can jump to the keyframe of the requestedpoint in time, and render the associated game chunks 150 as describedabove.

Play/Pause 1220—This button will pause the game if it is playing, orplay the active game session from the specific point in time where itwas last paused, if it is paused.

Playback Speed 1230—The “+” and “−” buttons will increase and decreasethe speed that the game is playing at, respectively, and the playbackspeed “1×” can be displayed. The use of keyframes may be particularlyhelpful in performance of this feature, as described above.

Time control scrubber bar 1240—this area represents the time that is inthe past for the game. It can be clicked on to set the time back to anearlier time. A tooltip that shows what time the user will jump to whenhovering over this bar can be included (not shown).

Time control scrubber position 1250—This is the current point in timethat is being played.

Viewed time 1260—This area of the bar indicates time that is in thefuture that is before the latest point in time that the user has alreadyseen. It can be clicked on to jump to a point in time in the future.

Unviewed time 1270—This area indicates the period of time that isavailable to jump to but that the user has not seen yet. This time canalso be clicked.

Jump to latest 1280—This button, when pressed, will jump to the latestpoint of time that the user has viewed, as indicated by the highlightedposition at the end of 1260. If the user is already playing back fromthis point, it will move the user to the latest point in time available,at the end of 1270.

The display at 1290 indicates the current point in time that the user iswatching and the maximum available time that the user can access,respectively.

In addition to the controls above, a spectator may select any area ofthe virtual landscape, which can be expansive, to view at any time, andcan further select a particular player for the camera view toautomatically follow. For instance, the spectator can mouse click on aparticular player in the game, and the spectator's camera view canfollow that player automatically. This can be achieved by having thespectator client 1200 focus on that player's data within the receivedchunks 150, either real-time, or at a selected time. Further, thespectator can switch from player to player at any time.

Turning back to FIG. 4, because the spectator's view is omnipresent, aplayer may be able to use that spectator's view to its advantage toobtain additional information about other players in the game. Toprevent this, a delay may be configured (Decision Block 2300). Ifconfigured, then the spectator grid 1100 may buffer the chunks by acertain amount of time, e.g., 30 seconds, before transmitting such datato a spectator, thereby enabling a delay, which would remove theincentive for an active player to attempt to view the game in spectatormode.

Moreover, the delay enables the spectator grid 1100 and/or spectatorclient 1200 to analyze the most recent data and notify the spectator ofupcoming events that may be of interest to the spectator. For instance,the virtual landscape of a game may be too large to view in detail inits entirety on a spectator client's 1200 screen, and the variousavatars may be moving in any different direction. At any given moment,an event could occur, such as a special move or a special achievementoutside the spectator's current camera view. Example events includechampion defeats, champion damage, events that lead up to championdefeat and/or damage, and game specific events such as the completion ofimportant team-based objectives, and status of key objects within thegame, such as status of key computer controlled avatars or objects. Tomaintain focus on the key events, the spectator grid 1100 and/orspectator client 1200 can be configured to monitor for such activitieswithin the buffer (which occur on the spectator's client 1200 at aconfigurable time later, e.g., 30 seconds) and cause the spectator'sview to focus on those specific activities when they develop and/oroccur on the spectator's client 1200. This directed view (Action Block2500) will ensure that the spectator does not miss key events as theyunfold.

Turning to FIG. 8, a more detailed illustration of a directed viewprocess (Action Block 2500) is shown. In general, one approach to ensurethat a spectator's view (e.g., as shown in FIG. 7) is focused on keyactivities and events within an active game is to follow one or morechampions that are associated with those events and activities. Whichchampion to follow can be dictated by a calculated “interest level” foreach champion. Generally, a champion's interest level correlates withthe distance between that champion and the key activities and eventsdescribed above when they occur and/or as they develop. In League ofLegends, factors used to calculate a champion's interest level include,for example: proximity of other champions within the virtual landscape;current health level; presence of debuffs (i.e., an effect given to achampion that decreases performance); participating in future eventslike damaging and/or defeating other champions or important teamobjectives; interaction with terrain elements, champion activities likestealthing and recalling to base, and so on.

In an embodiment, the buffered data from Action Block 2400 is monitored(e.g., in 10 second increments) for data, such as that described above,to calculate an interest level for each champion within an active game(Action Block 2510). The spectator grid 1100 and/or spectator client1200 then directs the spectator client's 1200 view to follow thechampion having the highest interest level (Action Block 2520). The viewis adjusted to also encompass nearby champions as well, to provide asfull view of the activities as possible. The spectator grid 1100 and/orspectator client 1200 then continues to monitor the most current bufferfor data that affects the interest level calculations (Action Block2530).

If activities develop during the game that cause another champion tohave a higher interest level, then the spectator grid 1100 and/orspectator client 1200 may shift the spectator client's 1200 view to thenew champion. However, if the identity of the champion with the highestinterest level shifts frequently, it may not be desirable to have thespectator client's view 1200 shift at the same frequency. To addressthis, hysteresis may be incorporated. For instance, if a new championgains status as having the highest interest level (Decision Block 2540),then additional thresholds are evaluated to assess whether to shift thespectator client's 1200 view (Decision Block 2550).

A number of threshold values may be utilized. For instance, even if anew champion gains status as having highest interest level, a spectatorclient's 1200 view may not adjust until the new champion's interestlevel is a certain percentage higher over the interest level of theprevious champion with the highest interest level (e.g., 20%). Anotherthreshold is a fixed value that the interest level of the new championmust exceed. These thresholds may decay over time after each shift inview and eventually settle at a minimum value until the next shift inview.

These thresholds, in combination with the interest for important futureevents ramping up linearly, ensure that the camera will switch early andprovide a lot of context to an event during periods of low interestelsewhere in the virtual landscape. When there are high levels ofactivity occurring in other locations, the shift may not occur untiljust a few seconds before the upcoming important event occurs to ensurethat the spectator client's 1200 view captures all key events properly.

Turning to FIG. 9, another exemplary user interface 3000 for a spectatorclient 1200 viewing an active game session is shown. As described above,the chunks 150 enable the spectator client 1200 to render real-time, orin near real-time fashion, game play from an active game, but with anomnipresent view that enables the spectator to view all game play withinthe virtual landscape. Having the omnipresent view of the game session,the spectator client 1200 may display a team status (or team fight) bar3100. The ability to display the status bar 3100 may be configurable byan administrator of the system 1000. For example, the administrator mayenable viewing of the status bar 3100 only for the game broadcaster (orcommentator), or for one or more game spectators (in the lattersituation, the game broadcaster and other game spectators may see thesame status bar 3100. The description herein thus refers to spectator asboth game broadcaster and game spectators, unless otherwise indicated).The administrator may also enable the status bar 3100 to be displayedautomatically as a default, not to be displayed as a default, or to bedisplayed only during directed camera mode as a default. The status bar3100 may be displayed with or without the shifting controls (shown inFIG. 7).

The status bar 3100 displays certain summary information of eachchampion of each team, e.g., of all 10 champions in a 5×5 game session,showing the champions of a team in a group (e.g., on the left) and thechampions of the opposing team in another group (e.g., on the right).The status bar 3100 helps the spectator quickly follow and understandthe game session, or helps the spectator understand certain informationwithout the help of a game broadcaster, who (if present) may want tofocus on other aspects of the game session. In an embodiment, thespectator may manually toggle, e.g., by pressing a key or combination ofkeys, the display of the status bar 3100 on or off. Or the spectator maydisable and enable one or more information display in the status bar3110. The information displayed in the status bar 3100 may include, forexample:

Team Health bars 3110—This information helps the spectator see whichteam is winning and aggregates the health of the champions and/or unitsinto a single representation. The team health bar 3110 may be calculatedproportionally, i.e., high-health champions or units represent a greaterproportion of the team health bar over low-health champions. Or the teamhealth bar 3110 may be scaled so low and high health champions representan equal proportion of the health bar 3110. This will help the healthbar fulfill its core role of communicating who is winning in teamfights.

Death Timer 3120—This information helps the spectator see which championis dead and the associated death timer, which when reaches zero thechampion is revived.

Pentakill Counter 3130—This information helps the spectator see whichchampion or unit is making kills.

Loss of Control icon 3140—This information helps the spectator see thestuns and other powerful hard-to-read effects on a champion or unit.

Ultimate/Summoner Spell Status 3150—This information helps the spectatorunderstand high-power, high-cooldown plays. The Spell status 3150 maypulse when the ultimate/summoner spell is activated.

Another example of information that may be displayed in the status barinclude the aggregate number of units and/or the number of units thatwere in the spectator's field of view that have been destroyed within apredetermined period of time. For example, if there were 100 tank unitsin the spectator's field of view initially, then 10 units were destroyedin a predetermined time period, the loss of 10 of those units may beidentified. If combinations of distinct unit types have unique abilitiesthat are only available when the distinct unit types are within apredetermined proximity, the availability of these unique abilities maybe displayed as well. For example, if a repair unit has a special “tankrepair” ability that is only available when in proximity to a tank unit,such ability may be displayed when the repair unit and the tank unit arewithin the predetermined proximity.

Turning to FIG. 10, another exemplary user interface 4000 for aspectator client 1200 viewing an active game session is shown. In theuser interface 4000, the spectator client 1200 displays a team status(or laning status) bar 4100. The status bar 4100 includes information asshown in the status bar 3100 above, for example, Death Timer 3120, SpellStatus 3150, and so on. In addition, the Health bars 4110 furtherdifferentiates the health 4111 of champions that are nearer to thespectator client's 1200 view, and the health 4112 of champions that arefarther from the spectator client's 1200 view, e.g., by showing brighterversus darker shades respectively. The threshold definition of nearversus far may be configurable by the administrator of the system 1000,or by the spectator, as will be described in more detail below. Thedisplay of each champion in the status bar 4100 also differentiates nearchampions and far champions. For example, a near champion 4120 has abrighter display and/or a different border, e.g., a silver border. Thefar champion 4121 has a darker display and/or border.

Turning to FIG. 11, another illustration of a directed view process(Action Block 2500) is shown. The system 1000 may automatically set theconditions and criteria for information to be displayed by the spectatorclient 1200. The conditions and criteria may also be configured by theadministrator, and may also change during a game session. For example,certain conditions and/or criteria during a game session may trigger thespectator client 1200 to display the status bar 3100, 4100, e.g.,changing from a global view to a view including the status bar 3100,4100.

The conditions include, for example, number of champions (e.g., 6 of 10)within a certain area of the virtual landscape, abilities used,champions being targeted, damage done to champions, and so on.

The system 1000 may also define conditions and/or criteria for includingor excluding certain champions, or for including or excludinginformation of certain champions in the status bar 3100, 4100. Theseconditions and criteria include, but are not limited to, selection ofmultiple targets (e.g., champions) based on visibility, and de-selectionof multiple targets (e.g., champions) based on visibility.

Selection of Multiple Targets Based on Visibility—

The system 1000 may select to display multiple entities, e.g.,champions, based on visibility status (Action Block 5100). Thisselection may produce a list of targets of interest. The criteria forsuch selection may include, but are not limited to:

The target is currently visible.

-   -   Visibility+range: The target is visible or would be visible if        it were moved a pre-determined distance towards the nearest        point on the border of the visible range or a pre-determined        distance from the center of the visual range.    -   Visibility−range: The target is visible and would be visible if        it were moved a pre-determined distance towards the nearest        point on the border of the visible range or a pre-determined        distance from the center of the visual range.    -   Wounded: The targets are not at full health.    -   In-Combat: Only targets that have caused damage to an enemy, or        received damage from an enemy, within a recently defined time        period.    -   Attacking: Only targets that are currently considered to be        attacking, for example, targets that have fired a shot or used        an offensive ability that is targeted at an enemy.

Two or more of the above criteria may be simultaneously selected.

De-Selection of Multiple Targets Based on Visibility—

Having a list of selected targets for display (Action Block 5300), thesystem 1000 may de-select one or more targets based on visibility(Decision Block 5400). The criteria for such de-selection may include,but are not limited to:

The target is not currently visible.

-   -   Visibility+range: The target is not visible and would not be        visible if it were moved a pre-determined distance towards the        nearest point on the border of the visible range.    -   Visibility−range: The target is not visible or would not be        visible if it were moved a pre-determined distance towards the        nearest point on the border of the visible range.

In order to prevent rapid oscillation of targets between the selectedand not-selected states, the system 1000 may provide buffering oftargets' information (Action Block 5200 and 5500). The buffering may bedone at the spectator grid 1100, the spectator client 1200, or at boththe spectator grid 1100 and the spectator client 1200. The buffering maybe based on, but are not limited to:

Buffering Selection Based on Time:

Buffering is triggered when a target that is not selected becomesselected by a selection algorithm (for example, an algorithm describedabove) (Action Block 5200). Instead of selecting the target, the targetis instead flagged with a timer stating it may be selected after apre-determined period of time (e.g., 5 seconds). Periodically, thetarget is evaluated by the selection algorithm. If the algorithm doesnot select the target, the timer is cleared. When the timer expires, thetarget is selected.

Buffering De-Selection Based on Time:

Buffering is triggered when a target that is selected becomesde-selected by a de-selection algorithm (for example, an algorithmdescribed above) (Action Block 5500). Instead of de-selecting thetarget, the target is instead flagged with a timer stating it may bede-selected after a pre-determined period of time (e.g., 5 seconds).Periodically, the target is evaluated by the de-selection algorithm. Ifthe algorithm does not de-select the target, the timer is cleared. Whenthe timer expires, the target is de-selected.

Buffering Selection Based on Distance:

When selecting a target based on visibility and de-selecting a targetbased on visibility, as described above, range based buffering (ActionBlock 5200) is achieved by using a smaller range for selection than isused for de-selection.

Buffering De-Selection Based on Distance:

When selecting a target based on visibility and de-selecting a targetbased on visibility, as described above, range based buffering (ActionBlock 5500) is achieved by using a larger range for selection than isused for de-selection.

The above methods of buffering selection and/or de-selection may becombined to smooth the selection and/or de-selection.

When the system 1000 selects multiple targets for display, statisticsmay be displayed for all selected targets in aggregate. For example, thecombined health of multiple selected targets may be displayed as asingle number. Other methods for aggregation include, but not limitedto:

-   -   Summation: The numerical value of each target is added, and the        total is displayed. The total may be displayed as a bar (e.g.,        health bar 3110, 4110), a numerical value, and so on.    -   Proportional Summation Each target is evaluated separately, and        its statistic is converted to a percentage based on a maximum        allowable range. The percentages are then summed. The resulting        percentage is then displayed as a bar (e.g., health bar 3110,        4110), a numerical value, and so on.

The system 1000 may present global and selected target informationsimultaneously. Global targets include all selected and un-selectedtargets. For example, turning back to FIG. 10, the health bar 4111represents the health of the selected targets (e.g., nearby champions),the health bar 4112 represents the health of the un-selected targets(e.g., far champions). In the example of FIG. 10, as shown in FIG. 10 a,the global targets include both the selected (e.g., nearby) champions4130, 4131, and the un-selected (e.g., far) champions 4132, 4133, 4134.By superimposing the selected-target bar 4111 over theun-selected-target bar 4112, the spectator client 1200 may visuallydisplay all three states in a single combined bar.

As described above, statistics for global targets may be displayed usingthe summation or proportional summation method substituting globaltargets for selected targets. In the same manner, statistics forun-selected targets can be displayed using the summation or proportionalsummation method substituting un-selected targets for selected targets.The difference in length between the global target bar (e.g.,combination of health bar 4111 and health bar 4112) and theselected-target bar (e.g., health bar 4111) will be proportional to thelength of the un-selected-target bar (e.g., health bar 4112), when thesame methods and scale are used for both sets of targets. For example,the selected-target bar 4111 represents the proportional total health ofthe selected team members; the un-selected-target bar 4112 representsthe proportional total health of the un-selected team members; theglobal bar is the proportional total health of global team members.

Various combinations of the above described methods of selection,de-selection and buffering may be used by the system 1000. For example,during a game session, the viewing area of the spectator's camera can beused for selection and de-selection with a time buffer for de-selection.A combined health bar for selected, de-selected, and global players canbe displayed allowing for the overall health status of the team to beunderstood within the local (viewable), off-screen (unviewable) andglobal (aggregate total) contexts.

In an embodiment, the spectator client 1200 displays ceremony orcelebration (not shown) when a big event occurs or is achieved in a gamesession. The big events include, for example:

Dragon Kill—This ceremony shows which team killed Dragon.

Baron Kill—This ceremony shows which team killed Baron.

Triumph—This ceremony shows which team won a fight, e.g., reduced theother team's health bar to zero.

Kill Streaks—This ceremony celebrates pentakills and possibly other killstreaks.

In another embodiment, the status bar 3100 and 4100 may be enabled forall players in a game session. In this embodiment, the spectator clientmay not display all information as that is displayed for spectator viewbecause a player does not have an omnipresent view as a spectator does.

It is noted that the system 1000 may also be implemented in non-videogame applications (e.g., online shopping system), or systems that candifferentiate between visible and non-visible targets (e.g., augmentedreality systems). For example, in a price checking system, when viewingproducts through an augmented reality device, products can be selectedbased on their visibility (using a selection method as described above,e.g., products cost less than $5, products on-sale, and so on) with abuffer to prevent quick selection (using a buffering method as describedabove). They can be de-selected when they are no longer visible (using ade-selection method as described above) with a buffer to prevent quickde-selection (using a buffering method as described above). The price ofeach individual item may be displayed up to a pre-defined limit. Whentoo many items are selected, the aggregate price of all selected itemsmay be displayed (using a combined statistics method as describedabove). This can be compared versus the aggregate price of allde-selected items.
